SPECIFICATION forming part of Letters Patent No. 317,175, dated `May 5, 1885.

Application filed August 18, 1884.

To aZZ whom it may concern:

Be it known that I, GEORGE Y. NAUERTH, of Cincinnati, Hamilton county, Ohio, have invented a new useful Revolving Book-Case, of which the following is a specification.

My invention relates to improvements in those book-cases in which a stack or group of shelves is suspended near its upper part upon a central post or standard, about which such stack may be revolved, so as to expose differ-` ent sides to view.

In my improvement several square shelves (of which each shelf below the top one has a central opening for the supporting-post) are supported at the desired heights, one above another, by quadruplex partitions, each composed of four rectangular boards, one end of each board being attached rectangularly to the side of one of the others at or near the latters mid-length, so as to constitute a central square well surrounded by four equal rectangular compartments, of which each is open in front, and is also (with the exception of a light removable, guard) open at one end. All of these shelves and interposed partitions are held to their proper relativepositions by tie-bolts, which, extending from top to bottom through holes provided in said shelves just within the four corners of thesaid well, are fastened by nuts at their lower extremities. The top shelf or board has a downwardly-projecting stud, which, occupying a socket in the top of the post, enables the entire nest or stack of shelves to hang perpendicularly and makes it possible to rotate said stack about said stud as a center.

, The top of such stack of shelves may be made available for holding a dictionary `or other work of reference.

In the accompanying drawings, Figure 1 is a perspective view of a revolving or rotatable book-case embodying my invention. Fig. 2 is a section on the line 2 2, Fig. 3. Fig. 3 is a section on the line 3'3, Fig. 2. Figs. a and 5 are respectively detached views of a shelf and one of the quadruplicate partitions. Fig.

rises vertically a round post, B, bearing on its (No model.)

top asocket, C, for a stud,` D, that projects i l downward 'from the uppermost of a series of shelves, boards, or ioors, E, of which all be:`

low the top one have a central orifice, e, for said post, and all have four smaller oriiices, e', for as many tie-rods, hereinafter described. Interposed between said shelves are quadruplex partitions F, of which each is composed of four rectangular boards of equal dimensions, andl of which each is attached by one end rectangularly to the side of one of the others at or near its mid-length, so as to form a central square well, L, surrounded by four precisely similar rectangular compartments, G, of which each compartment is closed at back and one end and is open in front, and is also open at the other end, except a partial closure by a removable open-work guard, H, that occupies staples J in the edges of the intermediate shelves and pits e in the bottom shelf or door. Said shelves and interposed partitions thus constitute several distinct stories capable of being quickly taken apart or of being as readily united firmly together, and with all the parts held immovably to their proper relative positions ,by means of four vertical tie-bolts, K, which, traversing the holes e in the shelves just inside the four corners of the well L, are fastened by nuts M at their lower, extremities. thus occupying the holes e just within the well-corners, serve to hold all parts of said frame-work rigidly to their relative positions, and to prevent lateral as well as vertical displacement. The topmost board,` N, may be secured by knob-screws I), and serves to wholl y conceal from view the tie-bolts and the stud,

`together with its oileduct d.

The tiebolts K,

IOO

I claim as new and of my inventionl. A revolving book-case body consisting of a series of shelves, E, the interposed quadruplex partitions F, which constitute a square Well, L, surrounded by four rectangular compartments, G, and the vertical tie rods or bolts within the Well at the corners, and by which the shelves and partitions are held together.

2. A revolving or rotatable book-ease cornposed of a series of separable square shelves, E, With interposed quadruplex partitions F,

constituting a square Well, L, surrounded by four rectangular compartments, G, held together and in place by the vertical tie-bolts K, concealed in the angles of said Well, substantially as set forth. Y

3. In a revolving book-oase, the body consisting of a series of shelves, E, interposed quadruplex partitions F, bolts K, by which the shelves and partitions are locked together, 2o

removable Wire guards I-I, and straps J, by which the guards are secured to thel shelves, the ends of the latter entering pits e in the lowest shelf of the series.

4:. In a revolving book-ease, the superimposed slab Q, so hinged to the top shelf as to be available as a reference-book holder, in

combination with the serrated props or racks R and springs S, occupying the central well, L, and with the knob or knobs rI, substantially as set forth.

In testimony of which invention I hereunto set my hand.
